<h3><span class="header-section-number">3.2.2</span> <code>Docker</code>的使用</h3>
<p><code>Docker</code>默认是需要<code>root</code>用户才能使用的，在<code>Windows上</code>我习惯于进入<code>Powershell</code>后执行下面的命令启动<code>Docker</code>：</p>
<pre class="shell"><code>wsl --shutdown # 先关闭wsl
wsl # 启动WSL
sudo su # 进入root
sudo service docker start # 启动Docker
su xiang # 切换会用户（非root权限）</code></pre>

<h3><span class="header-section-number">3.2.3</span> 如何从<code>WSL1</code>切换到<code>WSL2</code></h3>
<p>我在<code>Windows</code>上使用<code>Docker</code>遇到的一个很奇怪的问题是，我之前的版本是<code>WSL1</code>,<code>Docker</code>无论如何都无法使用，搜索半天也没有找到解决方法，索性将<code>WSL1</code>升级成<code>WSL2</code>，没想到问题就那样解决了。参考教程：<a href="https://zhuanlan.zhihu.com/p/356397851">知乎：WSL1 升级为WSL2</a>。下面是升级的过程：</p>
<ul>
<li><p>下载对应的内核更新包：<a href="https://link.zhihu.com/?target=https%3A//wslstorestorage.blob.core.windows.net/wslblob/wsl_update_x64.msi">点击下载</a></p></li>
<li><p><code>CMD</code>中管理员身份运行代码：</p>
<pre class="shell"><code>dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart</code></pre></li>
<li><p>设置版本</p>
<pre class="shell"><code>wsl --set-version Ubuntu-20.04 2</code></pre>
<p>其中的<code>Ubuntu-20.04</code>是通过代码<code>wsl -l -v</code>查看到的。</p>
<p>然后再次重启<code>WSL</code>即可。</p></li>

<h3><span class="header-section-number">3.2.5</span> <code>Docker</code>的使用</h3>
<p>进入<code>WSL</code>后运行下方代码运行<code>Docker</code>：</p>
<pre class="shell"><code>docker run -v /mnt/:/work -it omicsclass/rnaseq</code></pre>
<p>其中的<code>work</code>是不一定的，需要看镜像给的路径是啥。</p>
